SPECIFICATION forming part of Lettersratent No. 608,402, dated August 2, 189s.

Serial No. 618,425. (No model.)

Application filed January 8, 1897.

To all whom, it may concern.-

Beit known that I, HARRY E. DoDsoN,a citizen of the United States, residing at Springlield,in the county of Clark and State of Ohio, have invented certainv newy and useful Improvements in Oultivators, of which the following isa specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and v1o useful improvements in cultivators designed particularly for cultivating the soil about growing plants, as corn. f

The general object of the invention is to en-v able the operator while either riding on the machine or walking on the ground behind the machine to shift the cultivating-beams laterally and at the same time turn or deflect the wheels, so that if the beams are moved tothe left the body of the machine will run to the left by so zo deiecting the wheels, or Vif' the beams are moved to the right thegeneral frame of the machine will move to the`right by so deflecting the wheels. This object I carry into yeffect by pivoting the wheel-axles on vertical spin- 2 5- dles and by pivoting the forward portions of the cultivating-beams on vertical pivots and by then interconnecting arms on the wheelspindles by a cross-ban'and connecting levers or tillers which control the beams with said cross-bar, and by providing a hand-lever 4to operate the cross-bar and foot-levers to operate the wheel-spindle, so as to manipulate the parts by hand or by foot. Iregardthe levers or tillers combined with the vertically-pivoted cultivating-beams, which they swing laterally, as broadly new, and I regard the general combination with these levers or tillers and their pivoted beams as also broadly new in the sense of a new structural arrangement, though the general idea of shifting the beams laterally and defiecting the wheels, as above indicated, is not at this time new.

My invention further consists of certain subordinate arrangements or combinations and of certain details of construction, which will be hereinafter fullydescribed, and particularly pointed out in the claims.

In the accompanying drawings, on which like reference letters and ligures indicate cor- 50 responding parts, Figure l is a plan view of a cultivator embodying myimprovements; Fig.

`3 is a vertical sectional view of the machine on the line a: x of Fig. 1, looking in the direction of the arrow. Fig. 4 is a detail pespective view of a part of the wheel-deflecting and beamillustrating my invention, with parts broken away and others removed.

' I have illustrated in the accompanying drawings my improvements as applied to one type of cultivator, being a form wherein a divided tongue or pole A is secured to an arched axle composed of va lower bar B and an upper bar C. To the latter bar is secured a toothed segment D, supporting with the bracket E a rock-shaft F, carrying a lever G, adapted to be locked by a detent I-I to said segment; On the rock-shaft F is an arm l, which guides a pressure-rod J, connected to the cultivator-beam, and through a spring K is adapted to apply yielding pressure downward on the beam for the usual purpose of making the shovels take into the soil.

This

mechanism enables the operator to lift the beams from the ground .and lock them up also.

This lifting and depressing mechanism is in duplicate, there being one such for each beam, as shown in Fig.` l.

Another toothed segment L is carried by the bar C and supports a lever M, with a detent O to lock it to the segment.

This lever, through a rod Q, is

with the cultivator beams in the manner shown in Fig. 3.

' Iwill now refer to parts which enter into my improvements.

The letter ct designates the wheel-spindles, carrying stud-axles ZJ, on which are mounted These spindles are pivoted, as

the wheels c.

shown, inthe arched axle,and cach spindle carries an arm cand a foot-barf. The latter receives the foot,sothat while ridingonthe seatf/ the operator can deflect the wheels out ofthe line of draft of the machine, so as to cause the general `frame to draw over from one side to the other. To the arms c is connected by suitable swivel-joints 71y the cross-bar composed of parts ri, overlapped at their inner ends, as shown in Fig. ,lf, and fitted to a castingj and secured to each other and to the casting by a bolt 71'.. This bolt also connects with these parts a hand-lever l, extending back, say, aloner the seat, as seen in Fig. 3, or to a convenient distance for an operator walking` behind the machine. This leverty is fulcrumed on a bolt nl, carried by the arch, as seen in Fig` El, and when vibrated at ifs rear end its forward end shifts the crossbar 'i sidewise and through the arms e deflects the wheels on their vertical axes. Thus the wheels may be deflected either by foot or by hand, according,` as the operator is riding or walking.

Referring now to the means for shi fting the beams laterally, 2 designates cast plates fitted each on the under side of the crossbeam It, near each end, and having a circular .recess i), adapted to receive the circular boss 4, extending from a bracket 5, carrying a rod f5, on which the forward ends of the beams or drag-bars 7 are hun This bracket has a part S adapted to receive the lever or tiller U, which is bolted thereto, as shown at 11.0. Two bolts ll, with a disk l? fitted to a recess lil, serve to hold the bracket 5 in pivetal connection with the casting,` 2 and to secure such casting,` tothe cross-beam R. Thus the forward ends of the beams or drag-bars are pivotally connected on a vertical axis to the frame, so that by shifting the rear ends of the levers or tillcrs i) such beams, with their shovels, are laterally shifted. To effect such movements of the levers or tillcrs, I conneet them by links it with a T-lever l5, )ivoted on the bolt 7n, and thereby connected with the erosssbar 1f, so that when it is shifted laterally the T-lever 15, with the links It, also shifts and so likewise shift the levers or tillcrs fl. The tillcrs have clips lt, which, together with the rear extremities of the tillers, form jaws that embrace the cross-bar 'el to assist iu guidingr and supporting the rear ends of the tillcrs. Thus it will be seen that by operating the hand-lever g o r the foot-bars f the wheels are deflected, and simultaneously therewith the levers J are vibrated, and through the brackets 8 the beams are turned on their forward pivots and their rear ends, with their shovels, shifted laterally. It will be observed, too, by inspecting` the parts that if the wheels are turned to carry the frame to the left the rear of the beams will. be shifted also to the left, and vice versa.

As a means of locking the wheels and beams aga-inst deflection and laterally shifting in cases where itis desired to so use the machine,

I connect the rod Q with the third arm of the T- lever l 5 and thus prevent the T- lever from swinging on its pivot, as it naturally does to some extent when its pivot (the bolt 7.2) is shifted sidewise with the cross-bar 11. This rod Q is controlled by the lever M and its detent and locking-segment. \Vhen the wheels and beams are not to be so locked, then the rod Q is disconnected from the T-lever 115. As above observed, I regard this feature of beams pivoted at or near their forward ends on vertical axes and levers or tillcrs arranged to vibrate laterally to so shift the beams as a new feature in cultivators, and which by ex perienee I have ascertained to be effective and convenient in practice and in giving me a quick and yet positive control over the beams and their shovels. As also above observed, this feat u re, combined with the cross-bar and (.leflecting-wheels, constitutes a novel and valuable general combination which by experience I have ascertained is a successful and practical way of making this class of cultivators.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters latent, is-

l. In a cultivator, the combination with the main frame and its wheels swiveled thereto, arms connected to the wheel-spindles and a cross-bar interconnecting said arms, cultivater-beams pivoted to the frame, and levers or tillcrs on vertical pivots and connected to the beams at one cud so as to turn them` laterally on such pivots and to said cross-bar at the other, and manual means to laterally shift said cross-bar.
